System Resiliency, Reliability, and Dependability

As the number of devices per computational node grows larger and as computer systems rely more and more on multiple nodes for high performance, reliability aspects, especially soft-error tolerance, will become critical for single processors and consumer computer systems. In addition, energy/power efficiency is the number one concern for modern designs. Our approach is to research techniques that can provide resiliency where it is most efficient rather than where it is simple to do so. We rely on co-operative mechanisms that utilize multiple system layers, including hardware and software in many cases to achieve efficiency and resiliency. We are also working on resilience abstractions and mechanisms implementations with Containment Domains.

Programming, Runtime, and Compilation

As VLSI processor technology matures, parallelism, locality, and bandwidth conservation become more critical. However, current programming models and compilers do not explicitly address these issues, which leads to reduced performance and low programmer productivity. My first attempt at tackling these issues was as a member of the Brook stream language developer team. We designed the language for scientific computing that exposed parallelism and locality to the programmer, and worked on a sophisticated optimizing compiler targeting Merrimac. The language eventually shifted focus towards programmable graphics processors, and was released to the public domain as BrookGPU. Currently, I am taking part in the development of the Sequoia programming model and software system, which builds on our experience with stream programming and Brook. A Sequoia programmer is empowered to explicitly reason about and express locality and parallelism at multiple levels. The result is a high-performance application that can easily be ported to a variety of traditional and emerging architectures.

Memory System Design

The memory system is perhaps the most important component of modern architectures, because bandwidth is a severely limited resource. We are working on multiple aspects of memory systems design, including emerging memory technologies, error tolerance and resiliency, memory organization, and parallel memory systems.

Scalar Processor Architecture and Compilation + Virtual Memory Alternatives

Most current scalar processors still rely on an ISA that was designed in the late 1970s and does not reflect many changes in modern architectures. Therefore, I am exploring ISA designs that expose abstract, scalable, forward and backward compatible representations of internal modern microarchitectures to the compiler. The hope is that better communication mechanisms will allow the hardware and compiler to cooperate in achieving high performance, as opposed to the compiler tricking the hardware to achieve its goals or the hardware dynamically rediscovering information that is readily available to the compiler. One example of a cooperative ISA mechanism that I developed deals with register allocation. The Spills, Fills, and Kills technique allows hardware to rely on compiler-communicated liveness information to improve performance and reduce energy consumption.

Microarchitecture

High-performance single-threaded execution will remain critical in the future, even as processors turn more and more to data-parallel execution units. Regardless of this increasing use of parallelism, most applications contain significant portions of control code that is difficult to parallelize, and certain key algorithms simply have no known parallel representation. In addition to my research on scalar architecture and compilation, I have also targeted several aspects of optimizing single-thread execution at the microarchitecture level. These include the novel eXtended Block Cache for efficient and effective instruction supply, techniques for better dynamic instruction scheduling, and various predictive techniques for both performance and hardware efficiency. My includes exploring how existing and new microarchitecture features can be exposed in an abstract way to the compiler and programmer. As an example, I am currently working on extending a traditional general-purpose processor core with stream-architecture mechanisms to form a hybrid processor that can efficiently execute both control-intensive and compute-intensive code. Our goals include re-using existing microarchitectural components whenever possible.

Massively Parallel Processor Arch and Microarch (GPUs and Streaming)

Recently, GPUs and other throughput-oriented architectures have heralded a new age of performance and efficiency. I am interested in how to architect such processors and program them, including when multiple heterogeneous cores are integrated tightly. We have been working on such problems recently, and I also have worked on Streaming Processor architectures prior to the advent of programmable GPUs.

For example, the streaming supercomputer uses stream architecture and advanced interconnection networks to give an order of magnitude more performance per unit cost than cluster-based scientific computers built from the same technology. Organizing the computation into streams and exploiting the resulting locality using a register hierarchy enables a stream architecture to reduce the memory bandwidth required by representative applications by an order of magnitude or more. Hence a processing node with a fixed bandwidth (expensive) can support an order of magnitude more arithmetic units (inexpensive). This in turn allows a given level of performance to be achieved with fewer nodes (a 1-PFLOPS machine, for example, with just 8,192 nodes) resulting in greater reliability, and simpler system management. Merrimac is designed to be a streaming scientific computer that can be scaled from a $20K 2 TFLOPS workstation to a $20M 2 PFLOPS supercomputer. As lead architect my research involves all aspects of the system from hardware architecture, through the compiler and programming language, to the applications and algorithms.

Ultra Low Power Processors and Variation Tolerance

Not currently very active.

The most efficient operating point from an energy perspective is when supply voltage is close to the transistor’s threshold voltage. Unfortunately, at this near-threshold regime, process variations are greatly pronounced and operating frequency is low. We are developing architectural and circuit techniques that can tolerate the variations and utilize parallelism to overcome these limitations.

Network on Chip

Not currently active in NoC research

As the number of processing elements and cores on a chip continues to rise, the interconnection network grows in importance. We are developing novel NoC architecture, models for analytically predicting network performance and resource utilization, and a programming model that can enable the programmer to abstractly account for the network along with optimization algorithms.
